ShoeInk Oh, I wish it was part of the plot. But nope, you never get the characters growing to like them. Instead, you have the characters beating up caricatures of other nationalities, justifying their violence by painting the other party as the worst villains ever, praising China as number one, and then the protagonists are heroes for exercising violence and expelling all the "evil foreigners" from the mainland. That, or the characters laughing at how the antagonists are sent to Africa (which is painted as this "hell" for some reason, and never actually explored at all in the series), or justifying why "evil people" should be exiled to Africa.
Worst of all is the hypocritical rhetoric. "All Japanese are liars, they are not as honest as us Chinese." Literally said after the protagonist got deceived and almost killed by a bunch of Chinese fraudsters who wanted to rob him. I don't know if it's meant to be ironic, but that sort of mentality never gets corrected throughout the story. Instead, the protagonist proceeds to kill the Japanese characters and is celebrated as a hero for doing so. Wtf.
I tried reading past the nonsensical hatred the first few times, but when almost every single series repeats the same nationalist BS pattern, I gave up after a while.
